A lesser prairie-chicken is seen in this undated handout photo from the U.S. Fish and Wildlife Service (USFWS). The USFWS on Friday announced a plan to consider having the lesser prairie-chicken listed as "threatened" under the Endangered Species Act. The move by U.S. authorities to consider placing the bird native to parts of the oil and gas belt on the Endangered Species List has drawn the ire of some western lawmakers.
